Caution
CAUTION
For Security
Note that all external administrators are allowed to access the firewall when the Remote
IP is set to ‘0.0.0.0’ and Port is set to ‘0:’.
When Setting IP Range
The number of IPs for the ‘Local IP range’ and that for the ‘Remote IP range’ should be
identical when setting PPTP VPN.
For example, if the number of IPs for ‘Local IP range’ is 10 and that for ‘Remote IP
range’ is 20, only 10 calls will be set.
When Setting PPTP in Windows XP/2000
In Windows XP/2000, the administrator can use DHCP client. If VPN PPTP client is
connected while the DHCP client is operating, errors will be found. To prevent this
problem, close the DHCP client operation on the [Start] Æ [Program] Æ
[Administrative Tools] Æ [Services] menu of the Windows PPTP client installed.
When Changing Network Interface
Note that all IP sessions in working are disconnected for a while if network interface
(i.e., IP, Gateway, and Subnet Mask) is changed and finally applied while operating a
router.
When Using a Web Browser
Use Microsoft Internet Explorer(version 6.0 or higher) as the web browser for the
maintenance of GWIM. Other web browsers are not supported.

Table of Contents
When Using Dynamic IPs of DHCP, PPPoE, and VDSL
When a dynamic IP is used, the public information of ‘Port Forward’ and ‘Static NAPT’ is
not automatically changed. Therefore, ‘Fixed IPs should be used for the VoIP related
services that the setups of ‘Port Forward’ and ‘Static NAPT’ menus are required. In
addition, the ‘Fixed IP’ are used for the VPN services that the setups of WAN IP
addresses are needed.
When Changing DB
If the DB is changed in OfficeServ 7400 GWIM, the system restarts.
When Using a Private Key
The private key is provided with the package. The private key allows accessing SSH
from the outside. Thus, only trusted administrators should use the key.
When Deleting Internet Temporary Files
If GWIM package is upgraded, Internet temporary files should be deleted. Select
[Internet Explorer] Æ [Tools] Æ [Internet Options] menu and click the [Delete Cookies]
and the [Delete Files] buttons in [Internet Temporary Files] area. If these files are not
deleted, the webscreen of GWIM may not be normally displayed.

The GWIM supports 5 external WAN interfaces. The system can distribute the Internet access
traffic to each external interfaces by using the NLB function. For effective access traffic
balancing, the system uses the ‘Weighted Round Robin’ method. The NLB menu is used for
the setup of the Network Load Balancing function.
Configuration
[Network] Æ [NLB] Æ [Configuration]

Home Page
Table of Contents
Network Load Balance Configuration
The Network Load Balance Configuration is valid when at Leaset two network interfaces are
specified as the external network interface. For example, if T1 private line and ADSL line are
selectively connected to Ethernet 0 Interface (eth 0) and Ethernet 1 Interface (eth 1), the higher
weighted value is given to the eth 1 connected with ADSL line that its bandwidth is relatively
bigger and the lower weighted value is given to the eth 0. In this way, the load balancing according
to the performance of the external network line is performed. The system has the Failover function
that a different internal network interface line automatically backs up when any failure occurs in
some of multiple external interfaces.
The details by fields are as follows:
y
NLB Weight: Relatively higher load is distributed in the line of the external interface side
that higher numerical value is assigned. The weighted value for each external interface
should be the greatest common divisor (minimum irreducible unit).
Static Configuration
Along with the Network Load Balance Configuration, the Static Configuration window is used
to pass a specific external network interface line by separately specifying the traffic session to
satisfy a specific condition. In this window, entries can be added or deleted by clicking the

IPSec
IP Security Protocol(IPSec) provides security services in the IP layer through implementing
Internet Key Exchange(IKE). The security service is categorized into two services depending
on remote equipment: the services providing security tunnels between local subnet and remote
subnet, and between local subnet and remote host.
Even if IPSec can be set up to provide a security tunnel between local host and remote host,
the GWIM board is used for a gateway, not a host. Thus, this service is not used.
Since IPSec setting requires two gateways for a security tunnel, local configuration and remote
configuration have the same items.
IPSec Tunnel Mode
OfficeServ 7400 Data Server only supports the IPSec Tunnel mode.
The transport mode is not supported. In addition, if the WAN interface is used for
SERIAL, IPSec is not supported. Since a SERIAL line is used for a dedicated line,
IPSec is not required for the security.
Config
On the [IPSec] Æ [Configuration] menu, the administrator can add, delete, and search an
